CORPORATION F NEW YORK SEAL `Applitation led May 16, 1931. Serial No. 537,763.

Vseal of this character which is preferably made from a single sheet of metal, and in which the members areV formed by cutting and folding the metal in a simple and inexpensive manner without metal drawing operations; which does not require the use of any tools for the application and locking thereof; and which4 cannot be opened without tearing and mutilating the same. o

In the following drawing,'there is shown forl thepurpose of illustration, one form of device embodying 4the present invention.

.In the drawing y n Fig. 1 is a planview of the blank from which the seal is formed. Y l l Fig, 2 is a perspective viewV showing the complete seal ready to be snapped into locked position, and i Fig.y 3 1s a transverse section of the com- The seal is preferably formed from a single Y 'blank strip of sheet metal, stamped and bent to form a strap or shackle portion anda seal locking body at one end thereof, the other end of said strap being so formed that itrmay be locked andretained in said seal body; In the form illustrated, this seal body 11l is constructed in accordance with the invention disclosed and broadly claimed in myy priorPatent 1,783,938, issued December 2,

. 1930.l AIt comprises a housing section '12, a

closure section 13 having one end connected to oneend of said housing section, andthe other endY connected to thestrap 10, and an inner interlocking Vsection V14 having one end connected to the other end of said housing section. All of said sections are formed from a single sheet of metal, and each is bentinto channelshape, the sectionsbeing arranged in series lengthwise of the blank. The'section 13 is wider than the section 14, but nar-4 rower than the section 12, so that the section 14 may belocked inside of the section 12, and the locking means may be protected by the positioning of both sections 13 and 14 inside of the section 12.

The section of the blank for forming the housing section 12 has side extensions which may be bent along dotted lines 15 to form side walls 1,6. Each extension at one end is separated from the body portion by a slit 17, whereby thereare formed small flap sections 18 bendable, upon the dotted lines 19 to provide the inner plyof an end wall for the.

housingy section 12.

The inner interlocking section 14 whichis adapted to be bent into position within the housing 12 has a body portion 26 connected to the latter by an intermediate section which has a width substantially coextensive with the width of the flap sections 18, and is bent along the lines 24, so as to form the outer ply 20 of the end wall of the housing 12.

The inner section 14 preferably has extensions 21 which are bent upon dotted lines 22 to form side walls for this section, and is bent upon the dotted lines 25 to a position within the housing 12 with the top wall or body portion 26 of saidA section substantially in the plane of the outer edges of the side walls 16 as shown in Fig..2. l The body ofthe strap l0 has a section 13 which is bent in respect' to the housing on a Vline 31. This section 13 is adapted to form a closiire for the housing 12, and has side ex-` tensions 27 which arel bent on the lines 28 to form side wallsV 29.y Each of these side walls 29 is provided with an edge portion 30' bentto form inturned flanges upon the inclined edges of these side walls.

VThe side . walls 29 and 16 are each' shorter than the body portions to which they are connected, so that they are separated by two plane sections 32 and 33 preferably of equal length, and extending from the fold line When the seal parts are interengaged, these wall sections are spaced a slight distance to form an {open Vended transverse passage between i the fold line 31 and the ends of the side Walls Y ' Y 16 and 29. v5

If desired, this strap 10 'may' be providedwith one or moreholes 35 intermediate lof the ends thereof, so as to weaken said strap,

VVand .facilitate the bending thereof alonglopposite sides of said holes into the vposition shown in Fig. 2.

' It'will beunoted that the-entireV device is formedof a single piece of metal, thatthe formingis done entirely by cutting and bendinglw'ithout drawing operations, that the seal' may be applied and locked by a bending operationeasilyeifected by the fingers' without the usejof tools, that after the seal lis y locked,it cannot be opened without breaking or telltalef'mutilation, andthat the entire deviceris easy and'cheap to manufacture, and very efficient in operation.

In the 'specific construction illustrated in the drawing,ithe housing Vat .one 'end' of the strapl has. certain features similar to those shown and' ybroadly `claimed in my prior L Patent 1,783,938,'issued December 2, 1930.
